3.1: Quadratic Functions WORKSHEET
1. Graph each of the following functions by comparing to y  x 2 with a new (p,q) value and state
the required information. Check with a graphing calculator or table of values if needed.

3. Draw a sketch of a quadratic function with the given information.
a) vertex at (3,-2), y-intercept at 7
b) x-intercepts at -3 and 1, y-intercept at 1
4. Search “Quadratic Function Applications” on GOOGLE and list at least two real-life examples
of quadratic functions. You do not need to write any details about the application, just the topic
itself.
